Patented Dec. 17, 1935 UNITED STATES DREDGE BUCKET Wiliam H. Taylor,Phillipsburg, N. J., assignor to Taylor-Wharton Iron & Steel Company,High Bridge, N. J., a corporation of New Jersey Application December 18,1934, Serial No. 758,113

4 Claims.

My invention relates to endless conveyers oi the elevator and chaindredge type and provides certain improvements in connection therewith.

In U. S. Letters Patent No. 1,962,075, granted June 5th, 1934, on theapplication of Gerald Hillsdon Hutton, there is disclosed means toobviate spilling and loss of material from the buckets during elevatingand dumping operations, said means comprising an auxiliary lip in theform of a shallow trough-shape pan open at both ends, pivotally mountedon the back wall of one bucket and having sliding engagement with thefront wall of the next adjacent bucket so as to span or close the gapbetween the buckets.

The device of the patent, in principle and substance, is highlymeritorious but suffers the objection and disadvantage that it makes forfoundry problems and diiculties, frequently resulting in Wasters; inservice, the assembly 2'0 presents pockets in the slide area liable totrap material and so interfere with the efficient operation of the panseven to the point of breakage or deformation of the connecting parts;and, finally the matter of repair or replacement is a serious problem.

The object of the invention is to improve upon the construction andassembly of the device of the patent so that there will be no foundrydifliculties, and so that there will be no blind cavities in the natureof culs-de-sac or pockets for the trapping of material, and so that thematter of repair or replacement is reduced to a Very simple proposition.

The nature, characteristic features, and scope of the invention morereadily will be understood from the following description, taken inconnection with the accompanying drawing, forming a part hereof,wherein:-

Figure l shows in sectional elevation, part of a chain of bucketsembodying my improvements;

Fig. 2 is a section on line 2 2 oi Fig. 1;

Fig. 3 is a section on line 3 3 of Fig. 1; and

Fig. 4 is a detail of the pintle or pivotal mounting for the pan.

In Fig. 1, there is illustrated a chain of buckets having the Huttonservapan or non-spill element bridging the interbucket space andflexibly joined to two adjacent buckets for coordinate operationtherewith. The buckets 5, generally speaking, may be of the conventionaltype pivotally joined as at ll. The auxiliary lip or servapan isgenerally indicated at 'l and in accordance with the Hutton practice, itis pivotally mounted on the back wall of one bucket and in slidableengagement with the front wall of the next adjacent bucket.

The pivotal connection of the auxiliary lip is accomplished through theagency of a pintle or pivot pin 8 in cooperation with hollow engagingportions of the bucket and lip, the pin being held against turningmovement by T-head 9 lodged in a complemental socket and secured againstcasual displacement by a cotter pin Il).

The body of the auxiliary lip or pan is arched 5 transversely and alsoin the direction of its length so as closely to follow the contour ofthe bucket with which it has sliding connection and its generally troughor pan shape is dened by outwardly flaring side walls il. The latter areformed 10 with outwardly divergent lugs i2 terminating in aperturedbrackets i3 which constitute supports or carriers for demountable shoesi4 rigidly secured to the carriers as by bolts l5. The shoes have clipsit which bear against the end wall of 15 the brackets and the shoes areinturned or directed towards each other and they provide the slidingconnection for the pan by their cooperation with rails Il on thecomplemental bucket. The rails il flank the breast of the bucket and 20being outwardly directed, there is no excess clearance between the panand the bucket such as may be calculated to trap spoil and result indistortion or breakage of parts.

Having described the invention, I c1aim:- 25

l. In a bucket line, a pair of buckets, a pan pivotally mounted on thenear edge oi one bucket and shaped for close contour iit with the breastof the other bucket and having brackets, rails o-n the other bucketwithin the of the brackets, 30 and shoes removably mounted on bracketsand extending inwardly for lapping engagement with the rails to admit ofsliding movement of the pan.

2. In a bucket line, a pair of buckets, a trap- 35 ping lip flexiblyconnecting them, one of said buckets having laterally directed ribsconstituting rails, and the lip having rearwardly extending bracketswith replaceable shoes for sliding engagement with the rails. 40

3. In a bucket line, a pair of buckets, a trapping lip adapted to spanthe interbucket space and p-ivotally mounted in the mouth of one bucket,and slidably engaging laterally extended rails on the other bucketthrough the medium of 45 brackets mounted on the lip in flankingrelation with the rails, and shoes demountably carried by the bracketsand directed inwardly in lapping engagement with the rails.

4. In a bucket line, a pair of buckets, a trap- 50 ping member iiexiblyconnecting them, one of said buckets having laterally directed offsetsproviding outside rails, the trapping member having lugs extendinglaterally beyond the rails, and demountable shoes carried by the lugsadapted 55 and arranged for sliding connection with the rails.
